TL;DR: Phishing-resistant device-bound passkeys are moving from specialist protection to baseline authentication, with Yubico arguing that broad deployment matters more than protecting privileged users alone. The deeper issue is that backup methods, recovery flows, and app-based MFA often preserve phishing exposure rather than removing it, so authentication governance has to change at the lifecycle level.
Editorial analysis by NHI Mgmt Group, based on content published by Yubico: “5 common YubiKey myths for businesses – and why they don’t hold up”.
By the numbers:
- IBM’s 2024 Cost of a Data Breach report puts the average incident at approximately $4–5 million.
Key questions
Q: What breaks when passkeys are deployed only for privileged users?
A: The programme still leaves the majority of accounts reachable through phishing.
Q: Why do backup methods matter as much as the primary authenticator?
A: Because the attacker will use the easiest available path into the account.
Q: What do teams get wrong about phishing-resistant MFA?
A: They often measure success by the presence of a strong factor instead of the absence of weaker bypasses.
Practitioner guidance
- Expand phishing-resistant authentication beyond privileged users Require device-bound passkeys or equivalent phishing-resistant methods for the full workforce, not only administrators, contractors, or technical staff.
- Align recovery flows with primary assurance Review reset, replacement, and account recovery processes so they do not accept weaker proof than the primary authenticator.
- Reduce dependence on phishable fallback methods Remove SMS, OTP, and approval-based paths where they remain the easiest route to account takeover, especially for high-value roles.
Bottom line: Phishing-resistant passkeys only change the risk equation if organisations also govern recovery, replacement, and fallback paths.

Phishing resistance has become a baseline requirement, not a premium feature: The article reflects a broader shift in authentication governance. Once phishing becomes the dominant attack path, MFA that still depends on shared secrets or approval prompts is no longer an acceptable default for ordinary users. The implication is that IAM programmes must stop treating stronger authentication as a privileged-user exception and design for organisation-wide coverage.
A question worth separating out:
Q: How should teams design authentication so users stay protected throughout the lifecycle?
A: They should ensure users always have access to a phishing-resistant method through enrollment, routine use, replacement, and recovery. That means planning for lost devices, spare authenticators, and equal-assurance alternatives before an outage or compromise forces a weaker fallback. Lifecycle design matters because a secure primary method is not enough if users cannot keep using it.
